Hello,

the ActivePerl-FAQ (http://www.xav.com/perl/faq/Windows/ActivePerl-Winfaq8.html) says that users can use 

open( PORT, "+> COM1" ) or die "Can't open COM1: $!";

[download]
for opening a serial port. That is working on my system. *But*, not reading nor writing is working as suggested with read() and print().

I have tried to pass AT commands to my nokia 6310 mobile phone using the print function as in follows: 

open( PORT, "+> COM5" ) or die "Can't open COM5: $!";
print PORT "AT";

[download]
and i have tried to read feedback as using the following statement: 
$a = <PORT>;

[download]
but I cannot get any results or prints. it seems that this suggestion is over simplistic, i do not know what i need to do.

I was also trying to work with that carriage return (\r) rsp. line feed (\n)issue but still could not get any result.

can anybody help?!

I'm using ActivePerl-5.8.0.804.

With best regards

Motasem
